Switch(Config-if-Vlan1)# ipv6 address my-prefix 0:0:0:2008::2008/64
16.11 ipv6 dhcp client pd
Command: ipv6 dhcp client pd <prefix-name> [rapid-commit]
no ipv6 dhcp client pd
Function: To configure DHCPv6 prefix delegation client for the specified interface. The no
form of this command will disable the DHCPv6 prefix delegation client and remove the
allocated address prefix.
Parameters: <prefix-name> is the string with its length no more than 32, which
designates the name of the address prefix. If rapid-commit optional is specified and the
prefix delegation server enables the rapid-commit function, then the prefix delegation
server will reply the prefix delegation client with the REPLY message directly. And the
prefix delegation request will be accomplished by exchanging messages once.
Command Mode: Interface Configuration Mode.
Default: DHCPv6 prefix delegation client is not enabled by default.
Usage Guide: This command is used to configure the prefix delegation client on the
specified interface, an interface with prefix delegation client enabled will send SOLICIT
packets to try to get address prefix from the server. If the prefix is retrieved correctly, the
address prefix in the global address pool can be used by the ipv6 address command to
generate a valid IPv6 address. This command is exclusive with ipv6 dhcp server and
ipv6 dhcp relay destination. If the prefix delegation client is disabled for an interface,
then the address prefix which is get from this interface through prefix delegation client, will
be removed from the global address pool. Also the interface address which is generated
by the prefix delegation client will be removed, and routing advertisement with the prefix
will be disabled. If any general prefix has been configured by the ipv6 general-prefix
command, the same prefix learnt from prefix delegation will be disagreed.
Example:
Switch(Config-if-Vlan1)#ipv6 dhcp client pd ClientA rapid-commit
16.12 ipv6 dhcp client pd hint
Command: ipv6 dhcp client pd hint <prefix|prefix-length>
no ipv6 dhcp client pd hint <prefix|prefix-length>
Function: Designate the prefix demanded by the client and its length. The no operation of
this command will delete that prefix and its length from the specified interface.
Parameters: <prefix|prefix-length> means the prefix demanded by the client and its
